Granted: 1997-10-14
Abstract: Drill tools with eccentric bits for drilling a hole having a large diameter generally include a bit for swinging out to an eccentric position for drilling, and for swinging into a non-eccentric position for removal from a tubular casing.  Relatively complicated structures are required for effecting bit movement, and it is often difficult to remove the bit for replacement or repair.  A drill assembly offering a solution to both problems includes a mandrel for rotatable mounting in a tubular casing, a bit rotatably mounted in the mandrel, the bit and mandrel normally rotating together in one direction with the bit eccentric with respect to the mandrel, whereby the bit can bore a hole larger in diameter than the casing, a head on the bit for engaging a formation to stop rotation of the bit, shoulders on the bit and mandrel for retaining the bit in the eccentric drilling position, an inclined cam surface on the bit for engaging the bottom of the casing when the bit is moved upwardly to cause the bit to rotate in the other direction (opposite to the drilling direction) to a release position in which the bit is aligned with the casing for movement therethrough, and second shoulders on the mandrel and bit for limiting rotation of the bit to the release position.  The shoulders on the mandrel and bit are in the forms of projections which overlap in the vertical direction, each projection defining approximately one-quarter of the cylinder for rotation between the bit extended and the bit retracted positions.

Title: Process for non-destructive heat treatment of spooled silver coated high temperature superconductor
Inventor: WOOLF LAWRENCE D
IPC: H01B12/06
Filed: 1991-08-20
Granted: 2000-05-16
Abstract: A method for heat processing a superconductor wire which has a protective silver cladding includes the steps of attaching the coated wire to a spool and then rotating the spool to wind the wire around the spool in juxtaposed coils.      As the wire is being wound around the spool, the portions of the wire which are not yet coiled are drawn through a container which holds a paint that contains a silver diffusion inhibiting material. The diffusion inhibiting material is consequently deposited onto the silver cladding of the superconductor wire, and the coiled wire is subsequently placed in a furnace. The wire is heat processed in the furnace as appropriate for the particular type of superconductor material. The diffusion inhibitor material prevents diffusion of silver during the heat processing between portions of the wire which contact each other.

Title: Quartz glass doped with rare earth element and production thereof
Inventor: OYOBE AKIRA
IPC: C03C4/12
Filed: 1991-02-05
Granted: 1996-05-14
Abstract: Rare earth element doped silica glass according to the invention is prepared by doping silica-based glass co-doped with a rare earth element and aluminum additionally with fluorine and has excellent physical properties including remarkable light emission characteristics and an excellent capability of being fused with other silica-based glass.  Such doped silica glass provides high amplification gains and a wide wavelength bandwidth and therefore can be used as a material for manufacturing miniaturized optical devices.  Particularly, since the manufacturing process adapted to produce rare earth element doped silica glass according to the invention does not involve crystallization that normally characterizes the type of doped silica glass under consideration, the obtained doped silica glass is transparent and totally free from air bubbles.  As a method for manufacturing rare earth doped silica glass according to the invention combines means for producing articles made of porous glass and a solution impregnation method, it provides easy and effective means for manufacturing rare earth doped silica glass which is co-doped with both a rare earth element and aluminum and highly transparent and therefore can be used as a suitable material for active optical devices.

Abstract: Compensation for process direction photoreceptor motion in a Raster Output Scan system is provided by moving the cylinder lens located between the laser source and a rotating spot scanning mechanism, e.g., a polygon. The cylinder lens is moved in the process direction in response to error signals generated by a SOS detector and timing marks on the photoreceptor drum surface, or an encoder on the drum shaft. The lens movement is obtained by sending motion error signals to a piezo-electric actuator which increases in length to impart the desired motion to the cylinder lens.
